I rooted for them last February against the Falcons. We don't need yet another first-time Super Bowl champ before the Bills get one.
That said, I didn't root very hard, obviously. And I felt really good when they were down 3-28. But then when Brady went on a tear I rooted for him/them. Because they've already proven they're the greatest team ever. So who cares at this point?
All we can really root for at this point is Brady's retirement.
